Where can you buy traditional local artworks in Busan?

I'm looking to pick up some korean traditional local paintings as souvenirs before I head back home and I'm having a hard time finding a shop in Busan. I live in the Jangsan area so if anyone knew of a local art shop nearby that would be great. Also, If you know of any that are anywhere in Busan that are relatively easy to find (via subway) that would also be great, too.

I'm not interested in paying a fortune for paintings, but I'm also not looking for the cheap 'made in China' souvenir prints you see hanging around some outdoor markets.

Perhaps something from one of those small independent shops on the side of the road (that I haven't been able to find, lol) would be great.
